Born in Ibsley near Ringwood, Hampshire in 1872 to Albert Jenkin, a Denbighshire man, then employed as a Curate in Harbridge, Hampshire, Albert Mortimer Jenkin was educated at Llandovery College where he played for the college fifteen. Progressing to St John's College Cambridge, he made his debut for Swansea in 1893 and was selected to play for Wales against Ireland in Cardiff in March 1895. Wales won the encounter by a converted try to a try, thus avoiding the 'wooden spoon' that season. Jenkin kept his place against England in January 1896 but Wales were severely beaten at Blackheath (7 tries and 2 conv. to nil) and he was not re-selected when the Welsh Union made changes to the pack. Albert Jenkin had been made captain of Swansea's first fifteen for the 1895/96 season but resigned in the November ‘because of professional duties'. Jack Prescott took over as captain for the remainder of the season. Jenkin, a popular forward within the team, continued to turn out for the first fifteen. A student of mining, going on to become a mining engineer, Jenkin also played for Cambridge University and Glamorgan. He was ordained in 1902, moving to Roath in Cardiff and leaving for Central Africa in 1905. he performed missionary work for ten years on Lake Nyanza and during the 1st World War served as an army chaplain in East Africa. He later became Archdeacon of Pretoria. Jenkin returned to Wales and became Curate-in-Charge of St Peter's Church Newton in 1919. he died in Bromley in London in 1961 aged 88 years.
